Change the network interface that PaperCut listens on

PaperCut listens on all available network interfaces by default. If your server has multiple IP addresses (i.e. is multi-homed), PaperCut accepts connections to all these addresses. Alternatively, you can configure it to listen on a single, defined interface. To configure PaperCut to listen on a single network interface:

Open [app-path]/server/server.properties in a text editor.

Add a new line:

server.listen-interface=1.2.3.4

where 1.2.3.4 is the (static) IP address of the network interface for PaperCut to listen on.
